    • This disclosure deals with a variable fluid pressure regulator wherein the level at which the fluid pressure is regulated is adjustable. A member has a flow passage formed therein, and the fluid flows through the passage and out of the member, and a closure is positioned over the opening. The closure is yieldably mounted relative to the member and a spring urges the closure toward the opening. A recess or cavity is formed in the closure, and the fluid flows from the opening, into the recess, and then through a space between the closure and the member. The fluid pressure in the passage is a function of the spring force and the effective area of fluid pressure on the closure, and the effective area comprises the area of the opening plus any area of the recess which lies outside the margin of the opening. The regulated fluid pressure level may be varied by laterally shifting the closure relative to the opening in order to change the effective area.

    • This disclosure deals with a fuel injector for an internal combustion engine. The injector includes an injector body having a fuel metering chamber formed therein which receives fuel from a fuel supply. A plunger is movable into the chamber in an injection stroke to force fuel from the chamber and out of the injector through spray holes. A valve member is mounted in the path of fuel flow from the chamber to the spray holes, the valve member being movable between first and second positions. In the first position, the valve member seals the path and prevents air in the combustion chamber from mixing with the fuel being metered into the metering chamber, and in the second position the valve member closes the spray holes to terminate injection. During an injection stroke, the plunger moves the valve member from the first position toward the second position, and fuel injection takes place while the valve member is intermediate the first and second positions. The valve member is also subjected to hydraulic forces at the end of the injection stroke, which move the valve member into the second position in order to abruptly terminate injection.
